The Bubble Effect That Can Damage Steel
A single propeller blade needs high rotational speed to generate useful thrust, but ship machinery can only tolerate so much speed. A single blade also causes major vibration as its pressure pulses pass the hull.
High speed creates cavitation: low pressure behind the blade forms vapour pockets that later implode in higher-pressure water. Those implosions can damage propeller steel, so reducing rotational speed helps protect both the propeller and the machinery.
